ledger-dmk-implementation

Execute Ledger Device Management Kit (DMK) signing operations safely: initialize the SDK, establish a device session, verify device state, open the correct chain app, perform signing or device management operations, and return the result. Use when a developer needs to implement a signing operation (transaction, message, typed data), derive or retrieve an address from a Ledger device, send any command to a Ledger device, or perform device management operations such as genuine check, app install, or app uninstall.

W009: Direct money access capability detected (payment gateways, crypto, banking)

What this means

The skill is specifically designed for direct financial operations, giving the agent the ability to move money or execute financial transactions — such as payment processing, cryptocurrency operations, banking integrations, or market order execution.

Why it was flagged

Direct money access detected (high risk: 1.00). This skill is explicitly a Ledger hardware signing and device-management flow for blockchains. Step 5 defines chain-specific signer builders (e.g., SignerEthBuilder, signTransaction, signPsbt, Solana transaction bytes) and returns signed outputs. It includes explicit crypto-wallet operations (derivation paths, PSBT signing, typed-data signing, Clear Signing) and device actions that enable secure channels and app installs. These are concrete, purpose-built APIs to produce cryptographic signatures that authorize on-chain transfers — i.e., direct execution authority over crypto funds (even though human approval on-device is required).
